Pregled hidrodinamičkih istraživanja bunara sa horizontalnim drenovima numeričkim metodama
U radu je predstavljen pregled odabranih hidrodinamičkih istraživanja realizovanih primenom numeričkih metoda simulacije kretanja podzemnih voda pod uticajem rada bunara sa horizontalnim drenovima. Na osnovu pristupa u matematičkom i hidrauličkom tretiranju, kao i numeričkoj simulaciji bunara sa horizontalnim drenovima na modelima, predstavljeni su najznačajniji aspekti izrade hidrodinamičkih modela ovog kompleksnog tipa vodozahvatnog objekta. Metodologija obuhvata izbor: a) graničnih uslova za simulaciju prirodnih granica, izvora prihranjivanja i dreniranja izdani; b) primenjivanog stepena diskretizacije prostora obuhvaćenog modelom u planu i profilu; ...horizontalni bunari, hidraulika bunara, analitički modeli, numerički modeli, hidrodinamičko modeliranje podzemnih vodaĐorđije Božović, Dušan Polomčić, Dragoljub Bajić.

Automated blasthole drilling in surface mining
Milanka Negovanović, Lazar Kričak (2021)Све већи развој аутоматизације у рударској индустрији утицао је на увођење нових решења у области аутоматизације бушења минских бушотина на површинским коповима. Највећи светски произвођачи опреме за бушење развијају решења аутоматизације која омогућавају рударским компанијама да постигну најбоље резултате у погледу квалитета, продуктивности и оперативних трошкова. Решења из области аутоматизације бушења се крећу од операција даљинског управљања до потпуно аутоматизованог бушења, праћења података у реалном времену и разних специјализованих алата за управљање подацима који повећавају безбедност и продуктивност ...Аутоматизација, бушилица,тачност, бушење,рударство,систем даљинског управљања,безбедност, продуктивностMilanka Negovanović, Lazar Kričak .

Compaction of Municipal Solid Waste
Jovana Janković Pantic, Dragoslav Rakić, Tina Đurić, Irena Basarić Ikodinović, Snežana Bogdanović (2022)Regardless of the numerous activities undertaken to reduce municipal solid waste, its annual volumes continue to grow. In Serbia, the most common and the only one form of waste disposal is at municipal landfills with daily compaction and soil covering. Municipal waste compacting is one of the basic components of the disposal process. Well compacted waste takes up less volume and allows much safer storage. In order to better predict the behavior of municipal waste at landfills, it is ...Jovana Janković Pantic, Dragoslav Rakić, Tina Đurić, Irena Basarić Ikodinović, Snežana Bogdanović.

Prostorni položaj ofiolita istočne Vardarske zone: geofizičko-geološki model i njegove geodinamičke implikacije
Dragana D. Petrović (2015-12-29)Centralni deo Balkanskog poluostrva je geotektonski veoma složen. Tetis je zatvorentokom gornjeg mezozoika, a ofioliti na zapadu i ofioliti Vardarske zone predstavljajuostatke nekadašnjih okeanskih prostora. Najistočniji deo Vardarske zone razlikuje se odsvih ostalih ofiolita na Balkanskom poluostrvu i karakteriše se najizraženijim suprasubdukcijskimafinitetom. Istočna vardarska zona locirana je u centralom delu Srbije.Na severu se prostire do Apusena u Rumuniji, a na jugu obuhvata cetralni deoMakedonije i Peonias zonu u severnoj Grčkoj.
